Stick form: Glue sticks are solid and are shaped like a cylindrical stick, similar in appearance to a lipstick container. This design makes them easy to apply in a controlled and mess-free manner. 2.Adhesive type: The adhesive inside a glue stick is usually a PVA (polyvinyl acetate) or PVP (polyvinyl pyrrolidone) glue, which is safe for use on paper, cardboard, and other porous materials. It dries clear and is not overly aggressive, making it suitable for a variety of projects. 3.Twist-up mechanism: Most glue sticks come with a twist-up mechanism at the base, allowing you to expose more of the glue stick as you use it. This feature helps keep the glue fresh and prevents it from drying out when not in use. 4.Non-toxic: Glue sticks are typically non-toxic, making them safe for use in schools, offices, and homes. However, it's essential to check the label and product specifications to ensure it is non-toxic and safe for children. 5.Paper bonding: Glue sticks are primarily used for bonding paper, such as when crafting, scrapbooking, or assembling documents. They provide a smooth and even application, reducing the risk of wrinkles and warping. 6.Drying time: Glue stick adhesive typically dries relatively quickly, allowing you to work efficiently without long waiting times. Easy to use and store: Glue sticks are convenient to use and store. The container protects the glue from drying out, and the twist-up design keeps the stick readily available for use. "
